Packaging card having rigidity features

ABSTRACT

A packaging backer card has features running along at least one edge thereof to create rigidity in the card. The features imparting rigidity may be integral with the backer card and may lie flat, in the same plane as the backer card, in a flattened configuration. The features imparting rigidity may be formed by folding at least a portion of the backer card along at least one side, where one or more tabs may be used to retain and lock the folds in the folded configuration. The folded configuration may create one or more longitudinal fold lines that contribute to reducing the likelihood of flexing, bending or drooping of the backer card. The backer card may be used to secure an item, such as a medical device, thereto.

BACKGROUND OF THE INVENTION 1. Field of the Invention

Embodiments of the invention relates generally to packaging products.More particularly, the invention relates to a packaging card having oneor more rigidity features, such as a click-lock rail, providingadditional resistance to flexing or drooping of the packaging backercard.

2. Description of Prior Art and Related Information The followingbackground information may present examples of specific aspects of theprior art (e.g., without limitation, approaches, facts, or commonwisdom) that, while expected to be helpful to further educate the readeras to additional aspects of the prior art, is not to be construed aslimiting the present invention, or any embodiments thereof, to anythingstated or implied therein or inferred thereupon.

When packaging products, such as medical devices, often the device isplaced on a packaging backer cards. These backer cards are typicallymade of thin plastic, paperboard, cardboard, or the like, which does notoffer significant resistance to flexing, drooping or bending of thepackaging backer card. When the device is flexible itself, such as along, flexible catheter, flexing of the backer card causes the productto also flex or bend. While stiffeners may be attached to the backercard, such items often protrude from the cards, requiring substantiallylarger storage and shipping space.

In view of the foregoing, there is a need for packaging backer card thatcan includes integrated features for added rigidity that do not increasethe thickness of the backer card when the rigidity features are notengaged.

Acommercial implementation in accordance with the spirit and teachings ofthe present invention may be configured according to the needs of theparticular application, whereby any aspect(s), feature(s), function(s),result(s), component(s), approach(es), or step(s) of the teachingsrelated to any described embodiment of the present invention may besuitably omitted, included, adapted, mixed and matched, or improvedand/or optimized by those skilled in the art, using their average skillsand known techniques, to achieve the desired implementation thataddresses the needs of the particular application.

Broadly, embodiments of the present invention provide a packaging backercard having features running along at least one edge thereof to createrigidity in the card. The features imparting rigidity may be integralwith the backer card and may lie flat, in the same plane as the backercard, in a flattened configuration. The features imparting rigidity maybe formed by folding at least a portion of the backer card along atleast one side, where one or more tabs may be used to retain the foldsin the folded configuration. The folded configuration may create one ormore longitudinal fold lines that contribute to reducing the likelihoodof flexing, bending or drooping of the backer card. The backer card maybe used to secure an item, such as a medical device, thereto.

Referring now to FIGS. 1 through 7, a backer card 10 can include a backside 12 and a front side 28. The backer card 10 can be formed of variousmaterials, including paper, paperboard, cardboard, plastic or the like.In some embodiments, the backer card 10 is formed from a high densitypolyethylene material. The backer card 10 can be formed in variouslengths, depending on the particular application.

The backer card 10 can include a plurality of tabs 14 bendable along atab fold line 16. The tab fold line 16 may be generally in-line with anouter side edge of the flattened backer card 10. Each of the tabs 14 caninclude one or more engagement tabs 24 that may be moved in and out ofthe plane of the tabs 14. Tab cut lines 26 may be disposed within thetabs 14 to form the engagement tabs 24. In some embodiments, two tab cutlines 26 may be formed in mirror-image U-shapes to form two engagementtabs 24 that extend in opposite directions generally parallel with alengthwise axis of the backer card 10. Of course, other shapes for thetab cut lines that form the engagement tabs 24 are contemplated withinthe scope of the present invention, provided that the resulting tabshape is capable of interacting with the slots 22 as described below.

An outer lengthwise fold line 18 and an inner lengthwise fold line 20may be disposed adjacent each other and generally parallel with eachother along a length of the backer card near a side edge thereof. Insome embodiments, the outer lengthwise fold line 18 and the innerlengthwise fold lien 20 may be disposed on both side edges thereof. Thefold lines 18, 20 may extend from a top end to a bottom end of thebacker card 10, as shown in FIG. 1, for example.

To create the packaging backer card, a user can take the generally flatbacker card 10 and create a fold along the fold lines 18, 20. Each ofthe folds may be made upward and toward a central axis of the backercard 10 when the backer card 10 is placed with its front side 28 facingupward.

The user may then hold the fold line 18 flat against a base 32 of thebacker card 10, with the fold line 20 creating about a 180 degree fold.In this configuration, the engagement tabs 24 may align with at least aninner portion 22A of slots 22 formed in the backer card. Once all of theengagement tabs 24 are positioned within the inner portions 22A of eachof the slots 22 along the side of the backer card 10, the user may slidethe tab 14 along the base 32 to cause upward extending portion 34 anddownward extending portion 36 to tent and form an opening 30 along thelength of the backer card 10. Sliding of the tab 14 causes theengagement tabs 24 to slide along the slots 22 into an outer portion 22Bof the slots. A protrusion 22C can extend into the slots 22 providing alip 22D that may prevent the engagement tabs 24 from moving from theouter portion 22B back to inner portion 22A. While FIG. 7 show theprotrusion 22C as being rounded, in some embodiments, the protrusion 22Cmay be shaped more closely to a right angle to prevent movement of theengagement tabs 24. The protrusion 22C can be formed in various shapesprovided that the engagement tabs 24 may lock into place when moved intothe outer portion 22B of the slots 22. Such a locked configuration canresult in engagement of the tabs to establish a rigid card where thereis no intent of rail collapse during handling, shipping or use, thusprotecting the loaded medical device.

The tabs 14 may be formed along one or both of the side edges. The tabs14 and slots 22 may be arranged along the backer card 10 at a spacing tomaintain the folded configuration described above. In some embodiments,the tabs 14 and slots 22 may be spaced apart by from about 2 to about 8inches, typically from about 4 to about 6 inches. The number of tabs 14and slots 22 may be determined by the length of the backer card 10.

In some embodiments, as shown in FIG. 2B, the backer card 10 can includecard engagement features formed as engageable fingers 39 and/orresiliently flexible tabs 38. As can be seen in FIG. 13, a medicaldevice 70 may be held in place on the backer card 10 via theseengagement features. Placement and selection of engagement features mayvary depending on the specific application. While specific fingers 39and tabs 38 are shown in FIG. 13, other engagement features, as may becontemplated by one skilled in the art, are included within the scope ofthe present invention.

Referring now to FIGS. 8 through 12, a backer card 40 can include afront side 42 and a back side 58. The backer card 40 can include aplurality of tabs 44 extending from at least one lengthwise side edge.In some embodiments, the tabs 44 extend along each of the side edges ofthe backer card 40. In the unfolded configuration, the backer card 40and tabs 44 may lie in the same plane. The tabs 44 may include a tabfold line 46. The tab fold line 46 may be generally in-line with anouter side edge of the flattened backer card 40.

An engagement tab 54 may be formed at each tab 44 as a cutout extendingfrom the tab fold line 46 inward toward a central lengthwise axis of thebacker card 40. In some embodiments, the engagement tabs 54 may beU-shaped. Of course, other shapes for the cutout that form theengagement tab 54 are contemplated within the scope of the presentinvention, provided that the resulting tab shape is capable ofinteracting with the receiving tabs 52 as described below.

Thus, when the tab 44 is folded along the tab fold line 46, theengagement tab 54 may remain in the plane of the tab 44.

An outer lengthwise fold line 48 and an inner lengthwise fold line 50may be disposed along one or both sides of the backer card 40. In someembodiments, the engagement tab 54 may extend to or prior to the outerlengthwise fold line 48.

Receiving tabs 52 may be formed corresponding to each engagement tab 54and disposed toward a center lengthwise axis of the backer card 40. Thereceiving tabs 52 may be formed generally as a mirror image of eachengagement tab 54. The receiving tabs 52 may be bent upward and awayfrom the plane of the backer card 40.

To assemble the backer card 40 from its flattened configuration, a usermay fold each tab 44 upward along the tab fold line 46 to nearly a 180degree bend so that the tab 44 is against a top surface of the backercard 40. The user can then fold along the outer lengthwise fold line 48so that the engagement tab 54 is adjacent the receiving tab 52. The usercan press upward on the receiving tab 52 so that the receiving tab 52moves on top of the engagement tab 54. The user can then upwardly bendalong the inner lengthwise fold line 50 so that the section between thefold lines 48, 50 extends upward and away from the plane of the backercard 40.

Similar to the backer card 10, the tabs 44 may be formed along one orboth of the side edges. The tabs 44 and receiving tabs 52 may bearranged along the backer card 40 at a spacing to maintain the foldedconfiguration described above. In some embodiments, the tabs 44 andreceiving tabs 52 may be spaced apart by from about 2 to about 8 inches,typically from about 4 to about 6 inches. The number of tabs 44 andreceiving tabs 52 may be determined by the length of the backer card 40.

In some embodiments, as shown in FIG. 9B, the backer card 40 can includecard engagement features formed as engageable fingers 39 and/orresiliently flexible tabs 38. As can be seen in FIG. 14, a medicaldevice 70 may be held in place on the backer card 40 via theseengagement features. Placement and selection of engagement features mayvary depending on the specific application. While specific fingers 39and tabs 38 are shown in FIG. 14, other engagement features, as may becontemplated by one skilled in the art, are included within the scope ofthe present invention.

All the features disclosed in this specification, including anyaccompanying abstract and drawings, may be replaced by alternativefeatures serving the same, equivalent or similar purpose, unlessexpressly stated otherwise. Thus, unless expressly stated otherwise,each feature disclosed is one example only of a generic series ofequivalent or similar features.
